5. Unpacking:
Inspect the shipping carton for signs of damage during shipping and then carefully
remove the amplifier from the packaging. If any damage is present note in as much
detail as possible and take a photograph of the damage to send immediately to the
supplier. Retain all of the original packaging as this must be used if the amplifier is
to be returned to the supplier. Check all output connectors on the rear panel. If the
amplifier has been in a cold environment for a prolonged period of time before being
brought into a warmer area allow a suitable period of time before the amplifier is
connected to the AC mains supply to allow any internal condensation to dissipate.
6. Installation:
Position:
The amplifier should be installed in a cool, dry not excessively dusty area that has
sufficient space surrounding the amplifier to allow good ventilation. As the intake
for the cooling fans is from the front panel this should not present any problems but
both intakes should not be obscured in any way. Do not use the amplifier if it is in
direct sunlight for long periods. The rear panel of the amplifier should be no closer
than 15cm from a wall to allow the exhaust air to freely exit the amplifier for
optimum cooling efficiency.
As the amplifier is quite heavy make sure that the supporting structure is capable of
supporting the weight.
Connection:
The BLA600 requires the following connections in order to function.
The output of the transceiver should be connected to the RTX
f
input on the rear
panel with a suitable 50 Ohm patch cable terminated in PL259 UHF connectors. The
length is not critical but should be kept as short as practically possible.
The BLA600 has 3 antenna outputs
`ab
that may be configured on a per band basis
to the users requirements see section
7
. Default from the factory
Ant:1
`
is active
for all bands. The output from the antenna socket should be connected to a suitably
rated 50 Ohm cable, minimum rating 500W continuous at the highest used
frequency, (52 / 54MHz), terminated in a PL259 UHF connector. (We recommend a
50 Ohm low loss 10mm cable for the output side such as RG213 spec. or better).
This may be connected directly to a suitable resonant antenna of 50 Ohms resistive
input impedance which must be continuously rated at least to the maximum output
of the amplifier.
